Document Type and Number:

WIPO Patent Application WO1988004206

Kind Code:

A3

Abstract:

An apparatus (10) for sequentially drying both sides (8A, 9) of a paper web (1A). The apparatus includes a first drying roller (2A'') and a first felt (4A) extends around the first drying roller (2A'') for heating a first side (8A) of the web (1A). The first felt (4A) and the web (1A) extend around a first downstream suction roller (3A'''). A first guide roll (5A) guides the first felt (4A) away from the first suction roller (3A''') and a second suction roller (7A) is disposed adjacent to the first suction roller (3A'''). A second felt (4A') extends around the second suction roller (7A) and a second guide roll (12) guides the second felt (4A') towards the second suction roller (7A) such that the first and second felts (4A, 4A') define therebetween a web transfer section (14) so that the web (1A) is sandwiched between the felts (4A, 4A') during passage through the transfer section (14). A downstream second drying roller (6A) is disposed such that the web (1A) is sandwiched between the second felt (4A') and the second drying roller (6A) for heating a second side (9) of the web (1A).
